Non-conventional Christmas Dinners

Right then, I'm bored at work and looking for entertainment. Does anyone else of CasualUK tend to have non-conventional Xmas Dinners?

Story time for our household is that my wives family tended to not do a traditonal roast for Xmas dinners and instead they would do 'favorite meals' so whoever was cooking that year would make Lasagna, Steak, Duck Pancakes etc etc. Its a tradition we've carried through somewhat to our house where we will instead pick a theme so last year was various Pies, year before was authentic Mexican foods, year before was Chinese food done takeaway style. This years is 'Burger Christmas' where I'll be cooking a load of various burgers that are going to be served buffet style so we can add our own sauces and cheeses etc.

So does anyone else do anything other than a standard roast for their dinners and if so what is it?
